If you are looking for orchestral stuff but don't want to spend that much money, you might want to check out Miroslav Philharmonik by IK Multimedia.
I've been digging through this audio section of the forums since I've been trying to put together some semblance of soundtrack composition skill and thought I'd mention that I noticed this is on sale at the moment at
http://www.ikmultimedia.com/vigb/. The Philharmonik instrument is included in their group buy promotion, making it almost half off on its own and you get a second (and possibly more) instrument free. I haven't decided if I'm going to jump (I've already spent way too much picking up a handful of other things lately) but if you were going to pick it up, now sounds like as good a time as any.
